9. Linked Data: A way for publishing data on the web (with focus upon open
web standards and re-usability). Data is stored as triples (based upon the
RDF standard) and is query-able via the SPARQL standard
Linked Data…, web of data

10. Linked Data…, basic elements
1. RDF (Resource Description Framework)
▪ Triples (Subject-Predicate-Object)
▪ URI’s (Unique Resource Identifiers)
▪ Vocabulairies (re-usable glossaries & models)
2. SPARQL (Simple Protocol And RDF Query Language)
Data model
Query Language
Unique internet address of a data-element!!
Assertions about data-elements in sentences
Re-usable modeling elements

11. Source: W3C – RDF 1.1 Primer
Linked Data…, triples in knowledge graps

12. Linked Data…, ‘data clouds’
Paradigm shift
Clouds of Linked Data,
which are all knowledge
graphs (don’t think in
terms of tables and
columns anymore)
All data on the web is
accessible, connectable
and reusable via a URI
